Here in Kenya, infrastructure investment by the Kenyan government is very poor. Whatever money gets theoretically assigned to things like building and maintenance of roads and the power and water grids usually goes missing at various stages until the final project, if implemented at all, is shoddy.
Enter China, who have been directly funding infrastructure here. They are managing the supply chain and personnel themselves, and it's having a huge effect. Beautiful roads have sprung up around Nairobi in the last year especially, built using modern techniques and quality materials.
One can't help but wonder what concessions the Chinese government will eventually come looking for in return, because it's pretty certain that the debt will never be repaid in money.
